Tony, that is an unusual cell. I believe it's a LiPo (Lithium Polymer) in a round form factor, very unusual. LiPos actually don't have the highest energy density, in fact it's probably a bit lower an an IMR (LiMn) round cell. Their big advantage is low internal impedance. In other words, they can provide a lot of current without much voltage sag. They also have the best cycle life and shelf life.

That's a prototype unit that Breaktru is using. I believe Evolve (the maker) plans to mainly market these units to 3rd party manufacturers, though they will also be available to modders like myself and Breaktru. Though, I wouldn't use one myself since I design my own boards to perform a similar function.

Not selling, sorry. I'm beta testing for Evolv. It's a lot of mod for such a small package. Vapes great too.I think it's great that Evolv sends some prototypes out for testing before putting them out for sale like some of the other companies do.

* 5 clicks of the Fire button enters Locked Mode and 5 clicks to unlock.With the module in Locked Mode:* Holding the UP and Fire buttons simultaneously for several seconds and you access the Left Mode. Continue holding the buttons and you access Right Mode. This Flips the Screen 180 degrees.* Holding the Down and Fire buttons simultaneously for several seconds accesses the Stealth Mode and Normal Mode. Stealth mode allows you to vape without the screen illuminated.

When idle, the board goes into Power saver mode after a few seconds where the screen dims to half bright and then a few seconds more extinguishes.
